Abstract
We present the results from UV imagery of NGC 1275 obtained using the Goddard Ultraviolet Imaging Telescope (UIT). We are able to study the UV morphology down toµ249 ~ 25 mag arcsec−2. There are significant non-axisymmetric structures in the UV continuum associated with the low-velocity filament system. Continuum from the high-velocity system may also be present. The large aperture UV colors indicate that although the mass function extends to ~5M ⊙ , more massive objects are not present. This implies either a cessation of star formation during the last 50–100 Myr or a truncated initial mass function.
